New Beamline - Dec 8 2009

QA of PPV is at:

vernier scan with double-gaussian effective fit.

 I've had a lot of trouble stabilizing the fit with the two-gaussian beam profile (narrow gaussian + wide gaussian), so I've moved to something simpler - assuming a two-gaussian vernier scan p

Geometry Differential Framework [second test, material balance for TPCe03]

Abstract: To further test the prototype geometry differential framework, it is useful to examine the TPCe03 version of the TPC.

readiness of SL09g for W-production (1)

Preparation for W-production in December 8, 2009

 A single daq file from every run used for pp500 W analysis was produced with the chain:

Upsilon Efficiency versus eta-phi for electron daughter

Upsilon 1S+2S+3S used, weighted with:

(TMath::Gaus(upsRap)*upsPt/(exp(upsPt/2.2)+1)

I did not use just |UpsRap|<=0.5 to increase statistics

Does Fine Tuning GEANT Offer A Compromise?

    At the last spin meeting, the 10 keV thresholds defined by LOW_EM were questioned.

EEMC Simulation Studies - III

32 and 64 bits, tricks and tips

This is a collection of issues for SL5, 64bit kernels with 32 & 64 bits code support.

Quick PyROOT tests

The ROOT web site has a page How to use Use the Python PyROOT Interpreter, a good start for users of PyROOT.

Two issues w/ respect to simulation readiness

There are two issues being discussed within several groups (emc, phana, W) which may impact our readiness to run simulations for y2009.
